CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 60/256,238, filed Dec. 15, 2000.

BACKGROUND OF THE INVENTION

[0002] 1. The Field of the Invention

[0003] The present invention relates generally to recreational equipment, and more particularly, but not necessarily entirely, to boards for attaching on a user l's feet for bouncing on a trampoline.

[0004] 2. Description of Related Art

[0005] Various kinds of popular recreational activities require the use of boards such as snowboards, surfboards, and skate boards for example. The use of boards on a trampoline is gaining popularity both as a unique activity for performing aerial exercises such as “surf-bouncing” as well as an activity for practicing other board sports. For example, people wishing to improve snowboarding skills may use a trampoline while wearing a snowboard for practice purposes. However, using a conventional snowboard on a trampoline has many drawbacks. For example, the snowboard may cause damage to the trampoline with its sharp rigid corners. Also, snowboards are generally constructed of a hard material so as to be durable to withstand the forces applied while sliding down a slope. The hard materials of the snowboards increase the risk of injury to the user while jumping on a trampoline. Additionally, conventional snowboards have bindings which require boots to be worn to fasten the snowboard to the user's feet. The boots may also cause damage to the trampoline.

[0006] Attempts have been made to provide a protective covering for snowboards so that they may be used on a trampoline without damaging the surface of the trampoline. For example, U.S. Pat. No. 5,163,550 (granted Nov. 17, 1992 to Hawk) discloses a protective cover for snowboards made of an elastic elongated panel having an elastic cord around its outer peripheral edge. The elastic cord must be stretched to permit insertion of the snowboard. Only the bottom and edges of the snowboard are covered by the panel, and the elastic cord engages the top surface of the snowboard. The top of the snowboard is left uncovered to expose the bindings so that the snowboard can be fastened to the user's boots. However, since the top of the snowboard is exposed, the risk of injury to the user is increased due to contact with the hard top surface. Furthermore, damage to the snowboard may result from the repeated flexure caused by jumping on the trampoline.

[0007] In view of the foregoing state of the art, it would be an advancement in the art to provide a recreational board for use on a trampoline which is simple in design and manufacture and which minimizes damage caused to the trampoline. It would also be an advancement in the art to provide a recreational board which minimizes risk of injury to the user and which can be fastened to different sized feet without the need for specialized boots.

BRIEF SUMMARY AND OBJECTS OF THE INVENTION

[0008] It is therefore an object of the present invention to provide a recreational board for use on a trampoline which is simple in design and manufacture.

[0009] It is another object of the present invention to provide such a recreational board which minimizes damage caused to the trampoline.

[0010] It is a further object of the present invention, in accordance with one aspect thereof, to provide a recreational board which minimizes risk of injury to the user.

[0011] It is an additional object of the invention, in accordance with one aspect thereof, to provide a recreational board which can be fastened to different sized feet.

[0012] It is another object of the present invention to provide a recreational board which can be fastened to a user's feet without the need for boots.

[0013] The above objects and others not specifically recited are realized in a specific illustrative embodiment of a recreational board for use on a trampoline, the recreational board includes at least one soft cushioning layer and a support layer. The cushioning layer provides protection against damage caused to the trampoline and other objects by impact with the board. The cushioning layer also minimizes the risk of injury to the user.

[0018]FIG. 3 is a side, cross-sectional view of a second embodiment of a trampoline air board of FIG. 1, taken along section A-A.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] For the purposes of promoting an understanding of the principles in accordance with the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention claimed.

[0020] Referring now to FIG. 1 a trampoline air board, also referred to as a recreational board for use on a trampoline, is shown as generally indicated at 10. Board 10 preferably has an elongated substantially planar shape with its ends projecting slightly upwards. Preferably, a pair of cords 20, are situated in a central portion of board 10 for fastening the board 10 to a user's feet. The cords 20 are also referred to herein as holding members or elastic means for causing at least one of a user's feet to be held in a substantially fixed position with respect to the recreational board 10. Thus the cords 20 may include other structures such as straps for example within the scope of the present invention.

[0021] Preferably, the cords 20 are positioned so that the user's feet extend substantially perpendicular to the length of the board 10. Gripping surfaces 30 may be positioned on the surface of the board 10 to help maintain the user's feet in proper position. Gripping surface 30 may include a material having a coarse surface, adhered to the surface of the board 10 to increase the friction between the user's feet and the board 10.

[0022] Board 10 is preferably constructed in layers as best shown in FIG. 2. In one embodiment of the present invention, an upper cushioning layer 14, and a lower cushioning layer 16 completely envelope a support layer 12, so that the support layer 12 is non-removably fixed within the upper cushioning layer 14 and the lower cushioning layer 16. Preferably, the upper cushioning layer 14, and the lower cushioning layer 16 are made of a soft deformable material such as poly-urethane foam. However, it will be appreciated by those skilled in the art that other materials may be used within the scope of the present invention. Preferably, the cushioning layers 14, 16 are two separate layers which are fixed together with adhesive, or other techniques known to those skilled in the art, such that the support layer 12 is sandwiched between the two cushioning layers 14, 16. The cushioning layers 14, 16 may form an overhang 24 over the support layer 12 to form a protective barrier against the edge of the support layer 12. The cushioning layers 14, 16 may be adhered together at the overhang 24 such that the support layer 12 is completely covered, and not visible from the exterior of the board 10. The cushioning layers 14, 16 are configured to provide a protective covering that minimizes damage caused by impact between the board 10 and other objects such as a trampoline. Furthermore, the cushioning layers 14, 16 reduce the risk of injury to the user or other people who may be hit with the board 10. The cushioning layers 14, 16 absorb forces applied to them by compressing or deforming. Additionally, the cushioning layers 14, 16 preferably have an elastic memory so that when the applied force is removed, the cushioning layers 14, 16 return substantially to their original position.

[0023] The support layer 12 is preferably configured to provide stiffness to the board 10 so that the board 10 can maintain a desired form. Support layer 12 is preferably made of a material which also allows flexibility to prevent breaking of the support layer 12 during strenuous actions such as in “surf-bouncing ” on a trampoline. Support layer 12 is preferably made of a material such as plastic, fiberglass, metal or any other material known to those skilled in the art, to provide adequate strength to the board 10.

[0024] The fastening means for fastening the board 10 to a user's feet will now be described. The fastening means preferably includes cords 20 attached to the board 10 through openings 18 in the cushioning layers 14, 16 and the support layer 12. The openings 18 may be defined and reinforced by tubular through channels 26. Tubular through channels 26 may be formed of plastic, metal or any other suitable material known to those skilled in the art. Through channels 26 reinforce the openings 18 to prevent the cords 20 from tearing the cushioning layers 14, 16 and to help maintain the cords 20 in place. Cords 20 may be attached to the board 10 by passing the cords 20 through the openings 18 and placing knots 22 in the ends of the cords 20. Knots 22 are too large to fit through the openings 18 such that the cords 20 are attached to the board 10. It will be appreciated by those skilled in the art that other techniques may be used within the scope of the present invention to fasten the cords 20 to the board 10, such as fasteners, clamps or adhesives for example.

[0025] Preferably, cords 20 are made of elastic bungee cord material. This allows cords 20 to stretch to adjust to different sized feet. A user's feet can be placed beneath the cords 20 for easily fastening the board 10 to the feet. The elastic strength of the cords 20 firmly fastens the board 10 to the user's feet through a friction fit. Padding may be placed around the cords 20 to improve the comfort for the user. The user's feet are preferably maintained laterally in position on the board 10 primarily by friction between the users feet and the board 10, as opposed to an interference fit such as in straps, buckles, or bindings for example which abut the feet to block movement of the feet. The cords 20 preferably form loops or lines which reside in a single plane (the plane coincides with section A-A in FIG. 1). The user's feet may be gripped by the cords 20 within the plane such that the user's feet are fastened to the board 10, but the user's toes and heels may be lifted from the board 10. In the instant invention, the board is not locked to the user's feet. Therefore, the board may be released from the user's feet without causing injury to the user if the user falls on the board for example. All that is necessary to remove the feet from the board is to pull the feet toward the side of the board 10 with sufficient force to overcome the friction fit. Thus, the preferred fastening means for fastening the board 10 to a user's feet does not require special boots and corresponding bindings to safely fasten the board 10 to the user's feet.

[0026] Reference will now to made to FIG. 3 to describe a second embodiment of the present invention. As previously discussed, the presently preferred embodiments of the invention illustrated herein are merely exemplary of the possible embodiments of the invention, including that illustrated in FIG. 3.

[0027] It will be appreciated that the second embodiment of the invention illustrated in FIG. 3 contains many of the same structures represented in FIGS. 1-2 and only the new or different structures will be explained to most succinctly explain the additional advantages which come with the embodiments of the invention illustrated in FIG. 3. The second embodiment of the invention does not have a lower cushioning layer 16. Rather, the support layer 12 is exposed on the bottom. This allows the bottom of the board 10 to be more durable. The upper cushioning layer 14 protects the user and other objects from contacting the top of the support layer 12. Furthermore, overhang 24 of the upper cushioning layer 14 protects the user and other objects, such as the trampoline, from contacting the edge of the support layer 12. The upper cushioning layer 14 and the support layer 12 are preferably attached together by an adhesive or other suitable attaching technique known to those skilled in the art. Therefore, the upper layer 14 and the support layer 12 operate together as a unitary member.

[0028] In accordance with the features and combinations described above, a preferred method for bouncing on a trampoline includes:

[0029] (A) obtaining a board 10;

[0030] (B) placing a user's feet on the board 10;

[0031] (C) fastening the user's feet to the board by a friction fit; and
